The option below is how it works for law school. Your career office should advise you exactly how you should list it at the new school but generally, this is how it works.

For your undergrad, you might be able to just put the degree granting school down since that degree has already been awarded. However, I would check with career services at your new law school to see what they suggest.

No. It is my understanding the old law school can come off as soon as we receive grades from our transfer school. However, I am not 100% sure about this but I am pretty sure I heard that somewhere....Probably need to ask career services.

At my school transfers keep the old law school on the resume until graduation. Even though you may not like your old school, you obviously performed well there if you were able to transfer up. That means it's to your advantage to put it on there because it highlights your accomplishment.
